3ed7ecbb58 Fix ternary selection operator on float scalars in OpenCL kernels. 
According to Section 6.3(i) of the OpenCL 1.1 specification, the first
expression of the operator cannot be a float.

ad6fb3afc1 The 'static' storage-class specifier is not supported in OpenCL. 
This is documented in Section 6.8 (g) in OpenCL 1.1 specification.

e80bafdf66 fix for issue in getAngleShortestPath() 
Testing squared norm for <0 does not make any sense. In Addition giving the range of the return values is a great help to understand the descriptions.

6c9bfce975 Support btMultiBody soft contact using ERP and CFM. Also support custom relaxation parameter to allow successive over relaxation. 
Added demos for rigid and multi body soft (compliant) contact.
Will also add simplified Hertz compliant contact, by dynamically modifying the ERP/CFM to mimic a non-linear spring.
Note that btManifoldPoint is growing too big, we need to implement proper contact constraints derived from btTypedConstraint.

645a88176d Enable softness for btRigidBody contacts. This is implemented by some value (CFM, constraint force mixing) to the main diagonal of A. 
CFM for contacts use world CFM value by default, and can override with custom CFM value using the
BT_CONTACT_FLAG_HAS_CONTACT_CFM stored in m_contactPointFlags.
Boolean m_lateralFrictionInitialized is replaced 'BT_CONTACT_FLAG_LATERAL_FRICTION_INITIALIZED' flag stored in int m_contactPointFlags in btManifoldPoint.
Enable successive over-relaxation parameter (SOR) for contacts. btMLCPSolver uses global CFM.
In one of the next commits, contact softness will be enabled btMultiBody contacts.
Also need to review use of CFM in btMLCPSolvers (only world CFM is used at the moment)

069936218a [InverseDynamics] Add custom namespaces per configuration 
BulletInverseDynamics can be configured to compile using Eigen
instead of Bullet's LinearMath.

Adds a preprocessor defined specific namespace for each
configuration to produce linker errors if incompatible
libraries are linked (eg, builtin core library and
utilities for bullet types).

d6464ce40d add 'replay' command log feature: no mouse interaction during replay, and use a fixed number of sim steps in stepSimulation. 
workaround for reversed separating normal in gjk/epa when using very small shapes, detect case and revert normal.
use smaller world size (10 units versus 100) for higher resolution shadow map
use a hard-coded rolling friction of 0.2 for objects in physics server (will make this configurable)
fix loading of command log files, when platform features are different (64bit/32bit)
